Here we describe the orthotopic rat hind-limb transplantation procedure, which seems to be the gold standard in vivo model for composite tissue allotransplantation research.

Optogenetics has become a powerful tool for use in behavioral neuroscience experiments. This protocol offers a step-by-step guide to the design and set-up of laser systems, and provides a full protocol for carrying out multiple and simultaneous in vivo optogenetic stimulations compatible with most rodent behavioral testing paradigms.

Perineural invasion (PNI) is a common feature of head and neck squamous cell carcinoma (HNSCC), conferring lower survival rates. Its mechanisms are poorly understood. Utilizing neurites generated from murine dorsal root ganglia confined to a semisolid matrix, the pathways involved in the PNI of HNSCC cell lines can be investigated.

Analysis of ¹⁸FDG PET/CT Imaging as a Tool for Studying Mycobacterium tuberculosis Infection and Treatment in Non-human Primates

Alexander G. White^*1, Pauline Maiello^*1, M. Teresa Coleman¹, Jaime A. Tomko¹, L. James Frye¹, Charles A. Scanga¹, Philana Ling Lin², JoAnne L. Flynn¹

¹Department of Microbiology and Molecular Genetics, University of Pittsburgh School of Medicine, ²Department of Pediatrics, Children's Hospital of Pittsburgh, University of Pittsburgh Medical Center

Here, we present a protocol to describe the analysis of ¹⁸F-FDG PET/CT imaging in non-human primates that have been infected with M. tuberculosis to study disease process, drug treatment, and disease reactivation.

Behavior

Operative Technique and Nuances for the Stereoelectroencephalographic (SEEG) Methodology Utilizing a Robotic Stereotactic Guidance System

Amir H. Faraji¹, Zachary C. Gersey^2,3, Danielle M. Corson^2,3, James C. Sweat^2,3, Jorge A. Gonzalez-Martinez^2,3

¹Department of Neurological Surgery, Houston Methodist, ²Department of Neurological Surgery, University of Pittsburgh Medical Center, ³Epilepsy Center, University of Pittsburgh Medical Center

The SEEG methodology is simplified and made faster with a stereotactic robot. Careful attention must be paid to the registration of the preoperative volumetric MRI to the patient prior to use of the robot in the OR. The robot streamlines the procedure, leading to decreased operative times and accurate implantations.
